To all whom it may com:ernr' 'ing Portland; n the county of M lthemah and State of Oregon have invented new and useful Improvements in Mil'k Cans, of which the following is'a specification.

This invention relates tomilkcans or similar vessels, and has for an objec'tfto" provide a can which will be so constructed as to effectively preserve the contents there of during shipment ofthe can or when the same 1s placed in storage and which will contents of the can for a suflicient period to prevent the contents of the can from spoiling while in storageor during shipment. In the drawing, forming a portion-of this specification and in which like numerals of reference indicate similar parts in-the several views: Figure 1 is a side view of the can. Fig. 2 is a vertical section therethrough.

My improved can comprises an outer vessel 1 and an inner vessel 2, the former being rconstructcd' preferably of the intermediate section 3, the top section 4, and a bottom section .5. The bottom 5 is providedwith a depending flange 6 which is embraced 3 the lower walls 0]"; the section 3, and as illustrated, the saidflange is oflset, at 7, to provide a portion 8 which is spaced from the adjacent walls of the section 3- so as to;

form therewith an interveningpocketi) for the reception of the solder-10, this construc tion serving to form an efiective seal of the joint betweenthe flange 6zand the adjacent walls of the section3. aswill be unders tood.

In addition to the solder, as a means for fastening thebottoin; to the section 3, rivhts or similar equivaleixt fastening devicesll are extended jthroiighthe flange and through the. liiwer-iwalls of the section 3.

At the flipper rend, the section 3yis. provided with a' horiz ontally disposed inwardly ex tending shoulder 12 and rising from the shoulderis a vertical flange 13'. This flange is provided with an integral horizontally disposedflinwardly extending spacing portion 14 which embraces the inner vessel 2 ofthe can. -The top section 4 of the outer vessel embraces the flange 13 and is pro- I .vided with a shoulder 15' which bears against the shoulder 12 of the intermediate an integral depending flange 16 which mammary 29, 1511 Serial a... 641,233.

serve to retain the temperature of the liquid section 3. The said shoulder 15 is provided GEORGE s ErARD, or PORTLAND, OREGON.

\ H i embraces the section 3, being spaced there Be it knownthat I, GEORGE SHEPARD, a; subject of the King of Great Britain, residpocket 17- toreceive the solder 18. e I The section 1- extends upwardly. and infrom to "form therebetweehj an intervening wardly, at 19, from thespacing'portion 14. v

of the lower section and at-the upper end the said portion 19 is provided with adepending flange 20 which embraces theineck 21 of theinner vessel'2. The flange. 20 is offset, at 22,'f rom the neck 21 so afsgto provioletherewith an intervening pocket 23 for the solderf24s, The inner vessel 2 is pro;

the-vessel 2 are flared-outwardly to form a spacing. porti0nij 2 6;which bears against the walls of thesection 3 of the outer vessel,"as shown. The bottom of the'vessel 2 is'clo'sed by av bottom member 27 which is spaced from the bottom 5 of the outer vessel The" bottom member-127 is provided, with a flange 28 which is .fiared inwardly from the spac ing portion 2650 as to form therebetwe en an upper-section 4' of the euter intervening po'cket29 for the solder 30.

The, spacing portion 26 is perforated, at 31. The spacing portion lt is perforated, at 32.

The perforations 31 and 32 are for the purpose festablishing communi'cation with the space between the vertical and inclined walls of the inner and outer vessels 1 and 2 and the space between 21 of the inner vessel 2. This mouth member is closed by a cover 34 which comprises 4 the bottoms 5 and 27j -respectively. r

' A month member 33 is secured to the neck the spaced walls 35 and 36. The Wall 35..

of the cover is provpded with a suitable plug or seal 37 so as to prevent the entrance of air in the intervening space between the .walls of thecover after the formation of a vacuum therebetween. The upper member. 4 of the outer vessel 1 is provided with similar plug or seal 38 which also se'rvest-o prevent the destruction of a vacuum after the extraction of the air from the tween the vessels 1 and 2. a

10mm I L A mill; can comprising an outervessel including a bottom section, a top section and an intermediate section, the bottom section space be:

being embraced by the walls of the intermediate section and having a flange thereon spaced from the walls of the said intermedi ate section to form. an intervening pocket rounded by the intermediate section and the upper section, the said intermediate section having an external shoulder thereon disposed below the plane of the said spacing flange, the top section having its lower end seated on said shoulder and having a portion spaced from the walls of the intermediate section to form an intervening pocket therebetween, metallic cement located in the second pocket, an inner vessel located in the outer vessel and having its walls spaced therefrom to form an mtervenmgvacuum chamber therebetween, the said inner vessel having its lower end flared outwardly in the direction of the points of intersection between the bottom of the outer vessel and the intermediate section of the outer vessel, a

bottom for the inner vessel, the said second bottom being spaced from the bottom of the first vessel, the flared portion of the second vessel having passages therein to establish communication between the space between the first and second bottoms and the space 1-.

between the vertical side walls of the said first and second vessels, the top section of the outer vessel being offset inwardly at its upper end and spaced from the top of the inner vessel to form an intervening pocket therebetween, metallic cement in the .third pocket, a neck on the inner vessel, a closure for the neck, and means whereby the air may be exhausted from between the walls of the inner and outer vessels of the can.

In testimon whereof I afiix my signature in presence 0 two witnesses.
